Christopher, according the Ubuntu to Mainline kernel version mapping (http://people.canonical.com/~kernel/info/kernel-version-map.html), Ubuntu kernel 4.2.0-12.14 is based on Mainline kernel 4.2.1, but the error messages didn't appear while booting this Mainline kernel.
Actually, all these Mainline kernel versions boot without the errors described in the bug report: 4.3-rc3, 4.3-rc1, 4.2.2, 4.2.1, 4.2, 4.2-rc8. Am I missing something? Maybe I didn't test the right kernels. Ubuntu Kernel 4.1.0-3.3 is installed and boots without errors. Should I test more kernels? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1501431 Title: Various i915 Intel display driver crashes reported on syslog Status in linux package in Ubuntu: Incomplete Bug description: Computer: Dell Latitude E5440.
